Ursane triterpenoids from the bark of Terminalia arjuna

Five ursane type triterpene glucosyl esters including a new one, 2α,3β-dihydroxyurs-12,18-dien-28-oic acid 28-O-β-D-glucopyranosyl ester (1) were isolated from the bark of Terminalia arjuna, along with two known phenolic compounds. It is the first report of ursane type triterpenoids from this species.

One new ursane type triterpene glucosyl ester 2α,3β-dihydroxyurs-12,18-dien-28-oic acid 28-O-β-d-glucopyranosyl ester (1) and four known ursane triterpenoids were isolated from the bark of Terminalia arjuna.Figure optionsDownload as PowerPoint slide
